Suprefreakonomics Panned For Getting Global Warming 100% Wrong

Have Steven Levitt and Stephen Dubner finally gotten too cute for their own good? The pair are masters at contrarian interpretations of everyday things, but they’re getting shellacked over their take on global warming in Superfreakonomics, the sequel to the highly successful Freakonomics.

Tim Lambert over at ScienceBlogs rips them rips them to shreds over their oh-so contrarian take that really what we’re experiencing is global cooling:

Let’s look at what they got wrong. My Global Warming Sceptic Bingo Card is a bit out of date but they manage to tick five boxes: global warming is a religion, ice cores show warming comes first, ice age predicted in the 70s, water vapour dominates and climate modelling isn’t scientific. William Connolley stopped when he had found ten serious errors, so I’ll continue where he left off and see if I can find ten more. To make it more of a challenge, I’m just going to look at the extract that appeared in the Sunday Times entitled "Why Everything You Think You Know About Global Warming Is Wrong" (not yet available from their website). And remember, this is on top of the ten serious errors that Connolley found.

Unless otherwise indicated all quotes are from the Sunday Times extract.

1) "Yet [Ken Caldeira]‘s research tells him that carbon dioxide is not the right villain in this fight."

Caldeira has exactly one quote on his home page:

"Carbon dioxide is the right villain," says Caldeira, "insofar as inanimate objects can be villains."

Joe Romm asked Caldeira about the misrepresentation of his views and he told Romm:

If you talk all day, and somebody picks a half dozen quotes without providing context because they want to make a provocative and controversial chapter, there is not much you can do.

2) "Caldeira’s study showed that doubling the amount of carbon dioxide while holding steady all other inputs – water, nutrients and so forth -yields a 70% increase in plant growth, an obvious boon to agricultural productivity."…

The word “bitcoin” is as likely to garner feverish excitement as it is glaring criticism. The financial community sees speculative promise in the form of trade that currently has little to no regulation. Meanwhile, others argue that it’s a distraction that detracts from the overall longevity of U.S. financial institutions.

Bitcoin’s energy consumption has become a recent talking point in the debate. ...

"Keep An Eye On Gold" - Trader Sees Market Screaming "Gimme A Break Already"

Courtesy of ZeroHedge. View original post here.

Markets are screaming "gimme a break already," according to former fund manager and FX trader Richard Breslow, who notes that with Turkey on an extended summer holiday and Chinese equities getting a late-day boost from their friends, there has been little appetite for angst.

Breslow suggests "we should try it on for size and enjoy it while it lasts."

How Does Impact Investment Drive A Social Change And Profit?

By Nathan William. Originally published at ValueWalk.

For a prolonged time, investors have been satisfied with making money. They put little thought into where the money is invested, as long as the dividends are paid and the shares are doing well. But in the last decade, there has been a paradigm shift in terms of how and where investments are made. This alternative approach to investments outs an immense emphasis on corporate social responsibility, company ethics, and it’s all about giving back something worthwhile to the society and the environment as a whole. This wave of change is known as impact investment.

Doc Copper has had a rough go of it over the past 7-years and especially of late.

Since the highs back in 2011, Doc Copper has created a series of lower highs and lower lows.

Since the lows in 2015, it has experienced a strong rally, creating a series of higher lows, as interest rates and several commodities did the same.

In June Doc Copper may have created a double top at (1), as it was testing last years highs. Since hitting 2017 highs at (1), Doc Copper has declined nearly 20% in the past 10-weeks.

The decline now has it testing potential dual support at (2...

Weekly Market Recap Aug 19, 2018

Courtesy of Blain.

A good amount of volatility this past week, but once again indexes are just sort of hanging around as we work through some news items, specifically facing trade issues.  We ended last week with some hand wringing over Turkey – while nothing was really resolved, U.S. markets looked past that… however emerging markets continue their struggle.  The U.S. indexes have simply been range bound for weeks on end.

The Turkish central bank pledged in a statement Monday to provide “all the liquidity the banks need.” It also said banks would be able to borrow foreign-exchange deposits from the central bank at one-month and one-week maturities. Analysts said T...

There Are 3 Main Theories That Explain Trump's Approach to Putin and Russia-Which One Makes the Most Sense?

What do you think?

Thom Hartmann suggests that the "Manchurian Candidate theory" is the least likely explanation for Trump's pro-Russia behavior in "There Are 3 Main Theories That Explain Trump’s Approach to Putin and Russia—Which One Makes the Most Sense?" (below).  disagrees and suggests that Putin probably has "the goods" on Trump in "Trump’s Plot Against America". (To be fair, Hartmann acknowledges that his three theories are not mutually exclusive.) Jonathan Chait argues ...

Mapping The Market

Mistakes were Made. (And, Yes, by Me.)

Via Jean-Luc:

Famed investor reflecting on his mistakes:

Mistakes were Made. (And, Yes, by Me.)

One that stands out for me:

Instead of focusing on how value factors in general did in identifying attractive stocks, I rushed to proclaim price-to-sales the winner. That was, until it wasn’t. I guess there’s a reason for the proclamation “The king is dead, long live the king” when a monarchy changes hands. As we continued to update the book, price-to-sales was no longer the “best” single value factor, replaced by others, depending upon the time frames examined. I had also become a lot more sophisticated in my analysis—thanks to criticism of my earlier work—and realized that everything, including factors, moves in and out of favor, depending upon the market environment. I also realized...
